The first one is the simplest (o

the way Jim, I hope your games

Al last, VS Mcgabasic has hit

Hood me. m. Michat'l llnt*v ot
Peterbt trough was the first in
with a problem caused by the
Inierl.icc I unit attached 10 his
Specey. Well. Michael, you
need to cuter a Microdrive
command before loading YS
Mcgabasic, Ibis way you let
ihe program know iluii it's
dealing with shadow ROM-
I or example, if you enter the
CAT command before loading
up from cassette and ignore the
error message "MicoHiinvc not
present', this will simply
initialise the shadow ROM as
heirtg present
Michael has picked upon a
problem not covered in the

because il is! The en J ol ihe

forlornly onto The end of Line

rest falls into place.
One problem which bothers
quite a loi of you is how to

you 32x24 print ptwitions. Be
careful. I hough as any CLS or

When it comes to

Adams is an old hand
t
Facts, Your Spectrum,
14 Rathbone Place,
London W1P WE.
Often the most annoying
hardware bugs arc the
intermittent ones which only
crop up after a couple of
month's use. You start to wish
the equipment would get il
over with and just die. Siek
Mtc rod rives frequently come
into this category.
One of the first letters 1
received un this subject came
from Don A k tinder of North
Shields His original problem
was thai he kept gelling a
prompt saying 'Microdrive Not
Present" - and he assures us »
v\ as. The only way he could
cure it was by re- formal ting the
can ridge. A new Speccy jusi
added a new problem — the
'Drive Write Protected"
prompt keeps appearing
although the tabs on the
cartridges arc intact.
Well, what's needed here is a
bit of a clean-up on the edge
connector- If you can gel your
microdrivcio accept CA'I I
hut nolhing else then it's a safe
bet that the conned ion
between the drive and the
interface is loose or dirty. Use
an ink rubber In clean off any
gunge — actually it's oxide
caused by the gold on the
interface and the lead on the
Sped rum reacting like a
battery If that doesn't eure the
problem, make sure the
mierodrive isn't throwing a
wobbly — it's only conneaed
to the Spectrum by two screws.
lite problem's not quite so
simple lor Andrew Tarry of
Zimbabwe. His Microdrive
worked fine until one day he
heard a click in mid-load- Now
the motor works bul he keeps
getting the "Microdrive not
Present ' prompt. And, yes, he's
tried cleaning hut to no avail.
I'm afraid, Andrew, thai it's
going to have ro go back to
wherever it came. And that's a
mystery because as you point
out, there are no Sinclair agents
in Zimbabwe.
We'll leave Microdrive? for
the moment, though I have no
doubt we'll return to i hem?
B Duncan s telly keeps going
green every time he plugs his
Speccy into it. Prepare to turn
green yourself "cos it's reach
for the jiffy bag time, I'm
afraid. Your Spectrum's colour
synch signal is not being sent
and il will have to go back to
Sinclair (or repaired by
experts).
C P Hewitt of Stuney,
Stratford is also having probs
with (he visuals, though his
trouble is caused by a monitor.
He has modified his Issue 2
Speccy to run a composite
video monitor but he is getting
some annoying character- wide
dark bars down the whole of
the printable area of the screen.
It's all down lo Ihc ULA which
clocks the individual
characters. You have two
choices — there are plenty of
TV repair men who could solve
ihc problem or you could
change loan KGB monitor
using an RGB converter
(Adapt Electronics" is
excellent) which would
eliminate the fault.
Connecting a Speccy to a
television camera is a much
trickier problem. But this is
what Nigel Dallard wants to do
in order to produce ihc credits
for York Student Television.
Well, it's probably easier to use
the syne signal from the
computer to control the
cameras rather than the other
way round at Nigel suggests.
That can be done but it won't
be cheap and will require a
professional sync mixer.
Nigel also wants to know
where he can gel a curcuit
diagram for the Speccy so he
knows exactly where he's
wielding his soldering iron. It*s
not (hat easy, but CPC (0772
555034) produce a repair
manual or you could take a
look al a book I've found
... _,*..! l"_- „»»..„, tl J.
Mu riiwf from Melbourne
House.
D«*e Harm is having
in mble with a Compusound
beep amplifier He writes, "I
opened up my Speccy, inserted
amp, removed beep
loudspeaker, closed Speccy.
What do you know, no sound! "
Why on earth did you remove
the beep speaker? The unit is
designed lo clip onto irf
Removing the speaket is also
ajitrravaitng the other problems
which you're having.

K it possible lor you to

What do you mean, you're half
interested in buying
Megabasic? How can anyone
still be dithering ? This ir the
program of the year, and next
year for that mutter. However,
we don 't ha vr any plans to
bundle software and hardware
yet (give us time!), If you
really want a keyboard
without the confusing legends,
then you should take a look at
the Saga 2+ or Saga .1
keyboards, both of which
come with the option of having
only the standard
alphanumeric keys. Ed.

Faulty files are now a thing of the past! Using this second
instalment ot code, Andrew Pennell shows you how to recover
unloadable files from that Microdrive cartridge that's giving you
hassle. Take it away, Andrew ...
In issue & of our most illustrious
magazine, t got about half-way through
tie vising a Microdrive repair kit that
could .smc LI out faulty tiles m an article
called Running Repairs. Nnv>, to finish it
off, T have evolved a way of allowing the
recovery of un loadable files from car-
tridge,
SORRY!
Rut first, an apology, Pari one of this arti-
cle. Running Repairs,, was nut quite the
pristine job it might have been, and draw
with sharp eyes will have spoiled the tidd
buglet or two; the pity is. I can't even lay
the blame on our poor ©I* Ed (Poor yes.
but less of the 'old'. Ed.). The problem is
thai we get a sector list that's minus some
of the necessary data ... indeed, there are
quite a few sectors mining. As it stands,
this produces incorrect results in the
'check file* section.

Anyway, I've modified the code to
improve I he performance and, although
it's still not perfect — some sectors that
do exist may not be found on very full
cartridges, and some will he marked as
*bad' when they're not — this is not so
much of a problem now because one of
the functions of (he extra code given in
this issue, is for ii to act as an individual
sector read, and this achieves perfect
resuhs
Another problem in Running Repairs
was the code's position in memory —
RAMtop at 3fMKMI proved too low for
the eMra Basic. Thus. I've provided a
reiocalor program that'll shift the code
for you — that'll teach me to hand in part
one of an article before working out pan
two!

INTO ACTION
The menu has been extended to cover the
extra operation. 1 !; prohabb ihe most use-
ful of these is 'Examine sector*, which
searches a cartridge for a given sector,
and loads it (corrupted or not) into RAM
for inspection. Lines 6000 onwards load
the sector into locations 60000 cm,
revealing various details about it. Most
important here are the checksums; if
cither of these are incorrect it means that
the file of which ii is a pan will probably
not toad, and the sector should be
repaired — wh ich is exactly what option 6
does. You can usually tell if tape is phys-
ically damaged, because [he checksum
rcsuh will give a different value every
time you read it.
A sector is repaired by if being read to
address 60000 onwurds; Hums ihen writ-
ten out on to the next available sector,
with the checksums re-calculated. It's
not. of course, written back on to the
same sector as there's every chance that
the actual tape is damaged at this point.
Once a sector has been fixed in this
way, the 'bad' version should be

'removed' from the cartridge; there's not
much point in freeing the faulty sector for
further use. Option 7 achieves this by
marking it with a >trange filename full of
CHRS Os, That done, the next time you
ask for a sector list of the cartridge you'll
get a had sector with the name
■??????????"; this is normal, so don't try
to delete it again. The strange name will
not show up in a norma) CAT. As much
of [he utility is in Basic, you can re-
configure it to suit, using the extra com-
mands prnvided: check out the table of
commands given with this article
CODE CONSIDERATIONS
For those blessed with an assembler, it's
obviously a bit easier to enter the assem-
bly listing, rather than the accompanying
Hex, The listing, in facr, is a hit strange
for two reasons. First, it's fragmented,
consisting initially of the modifications
made to the code in Running Repairs. As
the original line numbers were chopped
from my listing (hat — at last something I
c an blame on someone else) the position
of each modification may not be clear. To
help. I've included at least one label in
each block. The only one that's a bit
vague is the mam extra section ... it
should go directly after TEMPA in the
code in Running Repairs. The **L+'
commands in the listing are assembler
directives, and should be ignored.
I he second odd thing about the listing
is that it uses a "macro". I've used one
called OLD to make it clearer when tail-
ing 16K ROM routines with the SK
ROM in place. The usual way to call a
routine is with two instructions — namely
a RS T# 10 followed by a OEFW - and
this is not exactly crystal clear; with the
macro defined, a much clearer tommmid
(such as OLD#20> can be used. Cur-
rently, the only assembler that allows
macros is the one from Hisoft — if you
use another, simply replace it wiih the
more king-winded version, (I cannot
claim any originality for this idea. The
shadow ROMs were written by Sinclair
Research using a similar macro, named
Ol.DCAL, but the Hisoft assembler
doesn't allow long macro names.)
And now for the code itself. To begin
with, there's a mod allowing the addi-
tional routines to be accessed — by
alteration of the JP instruction. The other
mods are to do with getting around the
'missing sector" problem, and the DEFB
0s are there to pad out the code so that it
ends up pretty much like the code you
saw in Running Repairs.
If you have a look at the code, you'll
see the macro definition, and that's fol-
lowed by the new syntax checker. Check
out the listing itself for further documen-
tation.
Anyway, that's about it. With this little
lot, you should be able to reclaim at least
some of your yn loadable files. The exist-
ing program does not alter corrupt data
from sectors — only the checksums —
and you could add a nice little editor
around line 6020 to do just that. Sorry for
the long wait between the two parts of
this article ... let's hope E don't have to
wait so long for you to come up with an
editor at line 6020! El*

What's slower than the C5?
Loading software into the
Spectrum, of course. So, speed
freak, SQ Factor has stuck the
go-faster stripes on his Speccy,
and taken it out for a spin. But
instead of aerodynamic spotters
he's gone for four fast tape
loading systems,
D'you remember the excitement when
the Microdrive was announced? The
iinticipation of speed — times never
before achieved on the Speccy. And
[hen, the long haul between promise Rod
delivery of the first not-quite-perfect
Microdrive v
Now you nn lunger have in wail an age
for them and the original, ridiculous
price of the cartridges has come down 10
an almost reasonable two notes. Bui the
Microdrive is no longer the only way of
super-charging your Spectrum, Without
going the whole hog and splashing out
more than the computer com on a disk
drive, you can LOAD at high speed in R
number of ways — and as you d expect
>".S has the dope. So, we told the dope to
draw up a chart of ah the info you need to
help you in your search for speed.
Our chart was prepared so you can
compare the features of each system in a
quick and easy to follow way. Ever} 'thing
thai cannot be compared directly in the
chart is discussed separately.
TIME CHECKS
The times in the chart were derived by
saving and loading the same program on
each system. For this, we used a truly
enormous BASIC program to wit:
lODlMaSOSOOO)
Once RUN, this program is about 35K
Bytes long! Several LOAD times were
averaged to get the times for the Micro-
drive and Wafadrive — both of these
require an 'access time" which lets the
drive search the tape for the file, as well as
the time needed to load the file once it
has been found. Access lime is not a
problem for the systems using ordinary
cassette tapes. The times for the Wafa-
drive were taken using a 64 K wafer
THE COMMON TOUCH
All of the systems:
■ Have a full through connection to the
Spectrum expansion port — or don't
obstruct it
■ Need no separate power supply
■ Can SAVE the usual types of Spec-
trum program or data or code.
■ Can SAVE a Basic program to autorun

And the one feature that runs through
them all is tape. 1 would recommend in
every case that you keep backup copies
in the standard tape format. You could
get caught out if you rely totally on any of
these systems to hold your important
bits. Each system has plenty of oppor-
tunity for operator error to cause loss of
data, and of course, fast moving tape will
wciir out eventual I y
GET IT TAPED
Both Wafa and Micro drives can corrupt
a file and make it unusable if you turn the
power on or off with the cartridge in the
slot. Abu take care because both forms
of cartridge are easily damaged (though
the wafer less so) and impossible to
repair, In particular, if the tape is pulled
out of the cartridge even a little way, il
will never go back.
The Sprint mechanism docs not pre-
28
vent you from changing directly from
rewind to play, and if you do so you will
probably damage the tape, as the speeds
involved arc higher than ni irmal. You are

tions, but it would have been better if this
was built into the hardware rather than
left to the user's memory, This formal is
standard format (just played faster) but I
would still use an ordinary cassette recor-
der to back up really important stuff.
Kwiktoad is bound to catch you out

may arise because it is trvine to do too

SINCLAIR MICRQDRIVES
The original Microdrivcs may
not be (he heal, bul they arc
the faMeM lytteu reviewed
and what's more they are now
reasonably priced, It's also
worth noting thai software
producers have been known
to write for ihem sometimes.

Mn n Hlrncs to serious UK —
hut I have been known to lose

mustn't be too hard on
Sinclair.
The 'full memory' bug
causes a crash if a large
BASIC program is LO Ailed
<>r even a small one if the
RAMTOP has been moved
down. This is caused by the
Microdrive's shadim ROM
not cheeking properly if there
is. space for both the program
and a 500 byte Microdrive
channel before I- O A Ding.
This can be bad news as it
crashes with the drives
running, which can corrupt
the tape when you switch off.
Further evidence of
dukinevi' is the fact that
inicrodrivc cartridges forma!
to a different size (in the
region of 90K) each lime you
format them. You may have
been advised to formal
repeatedly until you get the
largest number possible, hut I
believe thai the tew extra K
m a M peel. The whole
I mctte may merely foul your
drives into using part of the
tape which is on the edge of
reliability.
You can connect up to
eight drives to a -Spectrum via
Interface I. but vou onlv gel
one in the starter package.
Still, you akofet in RS232
port suitable for a printer (but
not usable with a full duplex
modern), and the Spectrum
network ports. It's said that
these will now pass data with
the latest version of the QI_
On the language front,
Microdrive syntax
unnecessarily tortuous, with
no defaults and tots of
needless punctuation
required. You have to specify
drive 1 even if you only have
the one. Wouldn't it be
simpler if number one MM
assumed to be present (father
than the network, say) unless
you told it otherwise? V ou
would save m symbols, many
of ihem needing two keys for
llu i. run man ds vnu are likck
to use most often with
Interface 1,
Instead of LOAD ""m:l;
why not use LOAD I for the
and LOAD n for the
network? I bal would activate
the error routine to page in
the shadow ROM just as well
as * does. Microdrive* were
long enough coming that
these rough edges should
have been knocked off well
before I hey were inflicted on
you and me. OK, you may
think I'm going on a bit, but
it's a fact thai the drives take
less time to LOAD a program
than it takes me to type in a
command telling them to do
it! I here is a saving grace
though — you can have a
program named "run" which
will LOAD and RUN jusl by
entering the keyword RUN,
ROTR0NICS WAFADRIVES
I he first thing you notice with
Wa fad rives is that you gel two
drives as standard. You also
get a bonus of RS232 and
Centronics ports. This must
make them a better buy than
a single Microdrive plus
Interface 1 at the same price.
lhe wafers themselves are
now more expensive than
Micro-cartridges, bul they
come in three sizes, 16K,
64K, and l28K;andthe
largest one has greater
capacity than a Microdrive
cartridge. The wafers are also
physically larger and rtmn
robust than Micro -cartridges,
with a sliding door to protect
the tape when it is removed
from the drive (lie access
time vanes according tOtbe
size of the Wider The shi irtest
for the ! 6K version was 6*5
seconds (worst case) as
opposed lo 45 seconds (worst
case) for the 12flK wafer. If
you "re after speed then go for
the shorter tapes, always
pt< tvided they're big enough
to hold your program.
There is a word processor
program in the package but
this is probably the on ji
software you will ever find
especially written for use with
the Wiifadrivc However,
Rotronies have converted a
number of games to wafers.
Transferring tape programs
on fo wafer is no more
Jitlicult than with the
Microdrive, However, you'll
use at least 2K RAM with the
wafer lysictn instead of the
half K needed for a
Microdrive channel, I his will
almost certainly make it
miptwablc io wafer many of
the larger games.
Wafer syntax is less of a
mouthful than the
Microdrive's as defaults arc

N i iw io the real ehtapie — * a

Of course. :>[ this price you'll
have to put up with a few
drawbacks l-irslly, you'll
obviously have to LOAD this
tape in the standard formal
before you can use the
routine to do fast LQADs.
Secondly, il has a really user-
violent syntax made-up
mostly of numbers which
to lv worked out, even
for Basic LOADs. Thirdly, il
will be less reliable ihssn the
hardware upgrades because it
is pushing a standard cassette
recordc i n i its imutv And
lastly, it is the least fast of ihc
methods we've looked at.
On the plus side, the
routines occupy only 220
Bytes, tr uses ordinary (but
not cheapo) cassettes, the
speed is a useful trebling of
the standard rate, and since
you lire likely Io be using the
same tape machine tor SAVE
and LOAD, tin: reliability
should be better than with the
commercial fast loading
games. And dun : Forget thai
h costs less than a tenth of the
price of the Sprint.
Probably the be&i use fur
Kwikk/md is to make
turboloading copies of your
favourite games rather than
doing frequent backups while
developing your own
programs, lor this purpose,
the cassette contains a header
reader as ft ell. to help you
ferret out the addresses
needed 10 make such copi
Then arc separate prograifu
lor loading and saving, and
the whole business of making
fast loading copies in (he I
place is fiddly and lime
consuming Still, the end
result is a tape that has i he
tricky bits in a short Basic
header program. So in
practice, once you've done
the hard work, you can just
use LOAD "" to get your
program to turhoload.
►Sflfl TRIALS
much wilh Standard hardware. Unlike
the Sprint, which physically runs the tape
faster to get Us speed, Kwikload crams
three times as much data onto the same
length of tape. This pushes the average
cassette recorder to its limits, and you
will need good tape to get away with it.
TO WIND UP...
Used in accordance wilh theinstr actions,
any of the systems will give you much fas-
ter loading than you arc used to, and
reasonable re liability. The Wafadrive
and Microdrive have the advantage of
disk-like operating systems which start
the motor and find files without you hav-
ing to mess with play, record and rewind
controls This is a definite plus and makes
up for having to cough up more for the
cartridges. A few billcr experiences with
ihc Microdrive bias me towards recom-
mending the Wafadrive or ihc Sprint, hut
if you're after speed then ihc Microdrive
must be a contender. More speed than
this can only come from disks but ihai is
another subject, and one thai we'll
explore when we're all rich Let us know
if il happens to you! Qs

So now we know, The reason nobody can
hear you scream in space is . . . they're all
frozen stiff. Or rather they are "cryogeni-
cally immersed', for Alien Scones with
the same sort of instructions as U Inm-
ate's other recent games. Enigmatic is an
understatement. Obscure, opaque,
mysterious or just plain umntelligahle
would be closer. Certainly, lots of long
word. 1 ; and not many facts to join them
Together.
Much easier to pick up the gist of the
plot by playing. All you need to know is
that you are a robot, sorry, cyhol, pro-
grammed to look iifter all the needs of the
frozen astronauts, off on a jolly jaunt to
colonise distant worlds. Unfortunately,
the ship has been invaded by aliens and
the life support systems have been
damaged. You now have to reactivate
theSC systems before the astronauts turn
into real stiffs.
Reactivation is achieved hy collecting
"thermolec valves' (different shaped
objects) and plugging them inlo the cry-
ogenic sockets (holes to plug in different
shaped objects). With 24 chambers to be
reactivated and only 5 initial replace-
ment packs (lives), it's not a task that'll he
completed firsi time out. You're going to
have to gel used «o the screams of a lot of
defrosting spacemen as they re-enter the
atmosphere. Luckily, on the Speccy
nobody' 1 1 hear them
Any resemblance to any other Ultim-
ate program is purely uncoincidcntal.
And sure, you're going to think you've
been conned by a clone when you first
load il up. But once you're into i he game
you'll see that ii's much more complex
than its predecessor and perfect* all the
techniques thai Knighdore prepared us
for.
So, now check out our map and start
planning your movements with the mic-
rowave on legs. O s
HACKER'S
We haw lift Qtf . ..Dave
Nicholls and Chris Wood
blast their way into the
backers " hyperspace of
Ultimate 's Allen 6.
"How do I become a
hacker? * That \ a question
more and more of you arc
writing in to us at V5toask.
I'o pul it hlunlty, » lol nf you
are trying to run before you
can walk. If you really waftj In
become j red-hot hacker then
you've got to be prepared to
put in some graft. I he best
vj\ to gain the necessary
experience is to gel out thin
and start writing machine
code progra ms of your own .
Only then will you start to get
the feel for [he hacking game.
Learning to hack is a bit
like teaming to read — first
you learn the 7M(\ instruction
set (your alphabet) and then
you 11 begin to recognise the
groups of instructions which
make up common
subroutines (words). Soon
you'll surprise you rselfwhh
the speed you've started to
hack at. instead of giving up
in despair, you'll be
recognising whole chunks of
code at a glance.
However, you'll always
come across games which
don't seem to fit in with ill
you've picked up previously.
3D games are the biggest
headache in this direction tad
what's Aden 8? — why, a 3D
game, of courac, The
standard way of tackling 3D
graphics requires a lot of
maths and .i loi of late nights
hut at least you'll be able to
hack into it. Alien a, like a lot
of arcade pmes, doesn't use
the bog-standard method, of
course, because that would be
just too slow. At first glance ,
ihc toughest part of the whole
priH.es.v is overwriting.
fliis means llial once a room
is set up, the programmer can
start filling it from the back'
so that the objects which
appear nearer to you
"overwrite" everything behind
them, The maximum number
of distinct objects in a room is
an incredible 56 and it only
takes one slip-up to ruin the
whole optical illusion.
Ultimate write everything
imluilly to a buffer high up in
memory and then the final
stage is locopy the whole lot
into screen HAM where you
can see it. Most games which
use a screen buffer (JSW is a
prime example) use the LD1R
instruction to copy to the
screen. Of course. Ultimate
have got to be different —
they copy line by line from
ihe bottom up 1 Flirl it's not
MiKxJy- minded news, just thai
[hey write their programs on a
machine Wilh an identity
- it only thinks it's a
Spectrum ( delusions of
grandeur, eh? — Ed),
Ulti mate's code is slick and
professional hut il bores mc.
Alien 8 is no except ion. ["his
time I managed to catch them
out though — in one part of
the program there's a jump
made to ihc very iu -\\
i uciiori. Its a bad Dibit to
get inlo, as it wastes space and
time, though it makes
assembly listings much mote
readable for us hackers. So, as
space isn't a problem m Alien
8, I'll let them off jusl this
once but it'll be a hundred
lines each if 1 catch them
doing it again!
For all that, I've got to
hand it to Ultimate, Alien fi
was a tough one to crack.
Since our last hack into one of
their games, they've made a
few improvements to the
speedloader they use — it's
even acquired a name,
Spccdlock At any rate, it's
been s couple of times round
the track since it was used foi
Decathlon.
A her [hal. it seemed a
doddle wriling an infinite
lives program. So easy in fact
thai I added the facility for
infinite time. Now the clock
wraps right round when it
ge L\ to zero. It's a bit of an
anti-climax when you run oui
of time anyway — we were
ex petting, if not a big bang,
(hen a bit of a whimper as the
space ship cntersthe
atmosphere and your
unfortunate astronauts
frazzle. Mo such luck.
The second program is a bit
specialised but ! rather like it
and thought you mighi too
1 1 |x it in and alter the tines
that are indicated and you'll
have a program that saves any
screen at any stage nf the
game to tape, just by pressing
Pause and then the S key.
Think of the fun you can have
— save a series Of Knees
onto tape, dump (hem onto
your printer and turn them
ntfQ your very own Alien 8
cartoon. Send them in so wc
Can all have a look. Software
prizes for the funniest!

insistence, I've made things a
bit easier this lime as some of
you had a few problems with
Underwurtde and
Ghmthwters ami he couldn't
help — he's i malty meJes ( w
what's ne* f Ed \ when it
comes, to helping win
hacking problems, It's now a
one stage operation. After
typing in the program and
running il you should get a
STOP statcmenl" message. If
you get 'F:.KKOR in DATA',
go fetch and cbecfc s >. »u* data
If all's well, ynu can now take
out line 25 and save the
program — nest time you use
it you can just run it. Then
enter "GOTO 3ft" and put
your fully rewound Alien 8
tape into the cassette recorder
and press play, The game will
now load and give you infinite
Hvcs and time. Dont worry
thai the name 'A lien H'
doesn't appear on the screen,
it's just that the program
ignores Ihc header on ihc
tape. If the second part of the
tape fails to loud straight after
the hrsi pari, you'll have to
rewind and Mart again. If
there are any el rors i tie
program keeps trying Ui
reload rather than stopping
wilh an error message.

Now I've said it before in the prc\ i
Codcbustcr articles hut it's worth repeat-
ing just in case there's anyone who still
doesn't believe thai software piracy is
illegal or wrong. It is, on both counts and
neither 1 nor Your Spectrum will ever
condone it. It harms the magazine, it
harms the software companies hut, worst
of alt, it harms you and me, the people
who buy software.
So. if you've got any ideas thai this arti -
cJe will aid you in your attempt to make a
killing al tape copying, you d be better
off reading Computing for Petty Crimi-
nals or simitar unworthy rags. I'm writing
only for the dedicated hacker who is
excited by the challenge of breaking into
programs 'because they're there', Nuff
said.
TAKING CONTROL
Generally the only way tc? get into a pro-
tected program is lo nobble it before it
runs I Once the code gets control, the
programmer will have fixed things so that
you can never seize the reins again. The
dedicated hacker gets around this incon-
venient I at I by using a customised ROM
incorporating his own BRkAK routines
Rut clever and /or unusually paranoid
Protection Artists have taken to adding
routines to check that the standard Spec-
trum ROM Ls still there before allowing
the program to continue!
Some programs do this during the
I.OADing. and then use up several
Kbytes in pure misdirection before get-
ting to a oil of code that unscrambles the
encrypted program and then erases itself,
disappearing up its own tailpipe. Others
apparently check for the presence of the
ROM constantly dun np play, and it
immediately crashes when the custo-
mised ROM is paged in.
CRASH BARRIERS
How do they check (hat the ROM is
there? Obviously they can't check the
whole ROM, byte for byte, without
I.OADing a copy of il. a pure waste of
I r>K, They can check the whole thing by
adding up all the bytes modula 25©,
which means throwing away any part of
I he sum which overflowed one byte, You
would then have only one chance in 256
of your custom ROM adding up to the
v-i me byte. However, this actually takes
some time, so it can hardly be used within
the action.
Usually only a few key hytes can be
checked, so which are chosen? Obvious
candidates are the various bits of the
initialisation code, starting at address 0.
I his address u often used as a 'crash and
hum' jump for destroying anything that
the program thinks might have been felo-
niously LOADed by a hacker. This is the
address that all the crash on BREAK
protection (apes rely on to wipe the
memory when you fiddle, and BO a Custo-
mised ROM might be expected to disable
this initialisation routine, as we suggested
in our last article,

'jump not zero' instruction being used
instead of a 'jump if zero', In my custom

able interrupt lo jump to my own de-trap
and BREAK routine.
The non-maskable interrupt is
actuated by its own line (NM1) on the
expansion bus being grounded momen-
tarily, and the non-maskable' means
that it can't be disabled by the 'disable
interrupt' instruction. This makes it an
obvious choice for the hacker's custom
ROM rewrite, and therefore a target for
the Protection Artist's search and des-
troy routine.
Checking lot hacker's rewrites is made
easier b\ I that there is not a lot 4 »f
code in the ROM that can be displaced
by one's own routines without causing
trouble with programs lhal use l Ik: ROM

CUSTOM BOARDS
kk;illy, a custom ROM or RAM bond
will be set up so you can easily switch it in
or out of the memory map. Indeed, with
RAM this is l necessity, or you would
never He able to start the Spectrum up in
the mornings. With IK of RAM located
in ihe lowest IK eif the uUdr ess space, the
sequence goes something like this: Turn

RAM, This will only work with a 1 k cus-
tom RAM, as the tape murines start at
about the beginning nl the second K, and
they would disappear when the RAM
was switched in. larger custom boards
will require a small M/C routine.
One thing to watch out for when using
RAM in the ROM area is th;U the Si
irum BASK actually corrupts the Erst

This seems to happen every time you
drop out of a program with STOP or an
error message or even when you enter a
command for immediate execution.
Ordinarily, this won't matter, because
fhjt pari of the ROM is only used at
power- up, but since the Protection Artist
is likelv to check here, it makes using a
ROM -in- RAM type of custom ROM
rather more difficult Why Ihe Speccy
ROM tries to write over itself is a mystery
to me. If and when I find the bit that's
doing it. I expect to be appalled at the
sloppines.%, hut as I haven't found It, I had
better control the rihald disparagement
for now.
Some programs load not just the whole
of the RAM. but also load over the
ROM, so if you don't page out your
ROM 'in- RAM custom isation while
I ( lADtng, it will be convened back to
the standard ROM contents!
If the custom ROM (or rewritten
RAM) can be switched in at exacity the
same time t hat the N M I is activated, then
no amount of checking up by ihe Protee-
linn Artist will keep you out. With
computer speeds, "exactly means that
you will have to use a bit of silicon to do
the switching, rather than just a double
pole mechanical switch, but if you have
already built yourself a piece of move-
able memory map then the exlra few
gates won't give you any problem.
EASY ENTRY
Not everyone. I realise, has the skill,
.or even the cash for building the
kind of hacking hardware we're talking
about here. Don't be downhearted.
though, as it still is — and always will be —
possible to hack into the headers of
Speccy progs, whatever the Protection
Artist hurls at you Hardware jusl makes
il casieT. or at least it used to before the
PAs started in on that loo.
However, it is occasionally possible to
catch the PA oul in an uncharacteristic
lapse. It is when he is feeling most secure

armour, to ahscntmindcdly drop the

has brought oul the laziness in some of
the breed, and ibey forget all they have

There is a very simple trick which I
have kept under my hat until now

programs. Luckily for you. I can contain
myself no longer. J his is one that anyone
can use, sans hardware, sans money, sans

thoroughly disables the BREAK key

may then decide to use a Basic routine for

he wants yon to Input a name, especially
if SAVing or LOADing a partly com-
pleted adventure. My, on tape. Certainly

Pining the tetcsi A/ *>r loncorlhenexl Sabre WW/spin-off
is all very well, but there comes it time when the old grey matter
needs a good storing.
AM Grant'* version of the popular card game Patience will
probably provid c j u$t t he son of bra i n- teaming fur Mhiit jroti ' re after
— it even rivals some of our KM) per cent machine code games
<l*W/„. nearly! E<L),
Here at the YS TowerWock. we're pretty confident thai you've
alt played Paifencrat one time ot another— there arc plenty of var-
iants to choose from! This, particular version, though, is the most
common.
The object of the game ts to turn every card face-up. The com
puter deals out seven columns nf cards face down the first
column containing u^[ « nc card, Iht second column two cards and
the top card from each column is then turned face-up. You
play the game hy manoeuvcring the cards around on-screen so that
they end up in descending order. However, you also have to make
sure you place a red card on a black card ant! vice versa. For exam-
ple, you can put the nine of clubs on the ten of diamonds, hut the
program won't allow you to put it on (he ten of ppndi
When you've done as much as you can with ihc cards you can
see. have a look at the bottom of the screen. Yes, you've guessed —
with only 28 cards on-screen, the rest of the pack can be used ... but
you can only gel at every third card, However, if you get stuck,
don't panic — just press the *C key and the deck will be shuffled
automatically.
There's an eighth column on-screen that's used to build up aces;
obviously, once you've got an ace in the 'ace slack' you can siun
building the vaibl up, just .is the other columns descend.
There are eight control keys to gel to know if you're going to
master this game ... so pay attention! 1 tic keys arc: "5" to move the
cursor left. T lo move the cursor right; r>' to put the 'held' card or
block of cards on to a column; ' 7' io pick up a card or block of cards
from a column; '4' lo pick up a card from the pack; '9* to turn over
the neat batch of three cards m the pack; *C to shuffle the pack;
and lastly, *y to quit the game.
All illegal moves are caught hy the program, except l hat il does
allow you to put any card in the empty columns, and not just a King.
If you don't consider this to be the 'proper' way to play Patience*
don't get angry with us ... have a little patience, and write yourself a
routine to "fix' it so that this hecomes an illegal move. And then,
write to Forum and (ell us how its done!

There are $ levels till
you gain an ox Ira HI*,
to there's plenty of
opportunity to
practise your arcade

Just when you thought that Jetman had been pensioned off, he pre-
pares* to make a Comeback, Yes, the star of sereen and monilitf.
Jttmmtua returned bom the comfort of hi^ South t oast g eria tric
hOttSC, forsaking all thoughts of a weekly pension, lo grace your
Spcctrums once more.
His current exploits invoke him in collecting ohjecLs such as
spanners, shovels and clamps, no douht with the intention of mak-
ing a n c* tra boh or two as a m os >n I igh t i n£ m otor mecha n ic. ( Th est
are iitird limes — Ed.) That or his bath chair is due for a service,
! 'nforlunalcly. Jetmtnt'n twilight years are nut destined to be
totally trouble free. The terrible lun at monsters arc mil to thwart
him (OK, this tart the Worthing yOM know anil love, bul we RCVCt
promised realism).
You control Jeiman-w'nh the following keys: A — up. /. — down,
M — right, N — left. If yi »u let our old chum touch one of the lunar
monsters, you'll lose a life and you Ofily have three at the stari.
However, if you manage to reach level 5, you'll noi only guin td
extra Life but you'll deserve a golden handshake, At I'.Swecannnk
make it as far as level .1 rjcrorc Jeiman gives up the ghost,
So. reach for the Grecian 2000 in J don't take an age typing in

CIRCE
Publisher, journalist and author of over 50 computing books. Tim Hartnell reckons he owes it all to
Uncle Clive, Sue Dertham finds out why ...
"I gucvs it alt Mailed soon after
] came to London from
Australia back in 197°. You
could fed" Ihm computers
we re goi n g t < > he the L ncul big
thing', but there was no way I
could afford a second -hand
Commodore PET for £4001
Bui then, in ls)80. Sinclair
Research launched the ZX80
for £ I H> and it all became
possible."
Five yean on. lim Hartnell
now runx the publishing
company. Interface
Publ leal tons, and has written
over SQtHtef for many micros,
including si* or seven loi the
Spectrum. Bui his main claim
to fame must Ik: the uniting of
Sinclair users under the banner
of ihc /XKO ZX8 1 Users'
Club, com pie I e with its own
computing nagwdne,
Interface It was the first
magazine Vilely dedicated to
ihe home computer user.
"1 think it's funny to look
h;*cls on those days — I
remember writing in Interface
that there was no point in
giving users more than IK as
no-one needed that much
memory! It was all so expensive
then anyway. Sinclair Research
wns charging £ J 6 for a gadget
to hold the RAM packs and
£12 for each 'Kr
-|1 Club was first
advertised in a three-line entry
in the hack of PCI* -and I
remember thinking it might
take a few months to take off
and not to be too disappointed.
I hat's how link f knew'
Within six weeks, ihe club had
V'MMl members!
"For the first few months. I
did a small newsletter and
approached a publisher frith a
mcw (o bringing out a 'proper"
magazine. But they turned out
to be a bunch of crooks who
just wanted to bleed the
membership dry. so I ended up
doing the Whole ihmg myself.
"The whole operation was
run from my home ~ wherever
you looked there was a mess of
typesetting and computer
printout! It became so difficult
to run thai in the end I went cx-
direeiory and used a mailing
address. Anonymity is u
wonderful thing at rimes!"
Of course, being a
computing personality does
have its ad van l ages.. ' I
remember being lhil- ol tin- iitsi
people to gel a look al the
ZXS I and Spectrum. When I
got my hands on the Spectrum,
ilieie were only three in
existence outside Sinclair
Research and two had already
broken. During ihc time 1 had
it, I was half-way through a
program and I'd lost the power
pack — 1 ended tip wiring up to
the power pack from an Acorn
Atom. Of course, as soon as
(he smoke started appearing I
unplugged it all ... but it still
worked!
What do you reckon to
Sinclair Research's approach
to Ms prinlueLs? "Well, if 1 was
to tell you thai way liaek in
I °4it), I was a*ked to check out
the machine that was to
become Ihc ZXB l and 1 had a
few problems with ihe ItiK
memory add-on. I doubt you'd
be surprised Bui, at the time. L
was a bit upset to find I'd lost
all my programming in what
was probably the world's first
CVtW recorded ' white- oul' ,, to
(he point thai I phoned up
Altwasser (the mam designer
of the ZX81 and Sot-arum)
and told him. f le said. "I think
you're asking too much of it.
Tim.", so nothing was ever
iU iik and for a year, users had
to put up with losing their
programs. Of course, the
boffins up at Sinclair Research
had i In device bolted down on
the bench and operated with an
industrial power supply — in
othco words, ii wasn'l designed
for human bcirii
"1 suppose J know why
people like me go along wiih
the situation, though, I enjoy
being part of the whole Simian
discovery process' ... I think
Sinclair users just want io help
the company get ii right. But
it's ,i fast moving tadutrj tod
ihese things should be put io
rights nowadays be I ore the
product comet on) But. it
defence, it's also a young
industry ... and, although we're
talking about the Z XKO and
ZX81 as if they're pan of
ancient history, in real terms it
was only a couple of pairs < if
sneakers ago!"
How about all the hooks
you've written? "Well, I guess
(hat my success as a publisher
and author is all down to Uncle
Clivc's/XHO (like I'd Written
Mtikinft IhfMastQJ )t>ur
/A 80. 1 never looked back I
haven't had a really good
review OffooeoJ my books in
the UK lor years ... and it does
hurt me. On the Other hand, it's
pleasing to know I ha I IV
encouraged a In of
programmers "
And whai of ihc future?
"Well, the Spectrum will he
with us for many a year ... in
whatever form] Hut I'm not
nirt piogramming will ever be
like the 'okl days', d IBM)
sound silly, hu I I used to enjoy
finding out all about the ZXHO
while I balanced a frozen milk

cool it down?"
